Shrub rose plant named `Poulurt`

ABSTRACT

A shrub rose variety producing yellow buds becoming near white to light yellow flowers.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rosewhich was originated by crossing as seed and pollen parents two unnamedand undistributed seedlings of our creation. The varietal denominationof this new rose is `Poulurt`.

Among the novel characteristics possessed by this new variety whichdistinguish it from its parents and all other varieties of which we areaware are its attractive flowers borne on a healthy and hardyfloriferous plant useful in landscaping.

Asexual reproduction by budding of the new variety as performed inWatsonville, Calif., shows that the foregoing and other distinguishingcharacteristics come true to form and are established and transmittedthrough succeeding propagations. Other known forms of asexualreproduction may be also employed, such as vegetative cuttings,micropropogation and grafting.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of the new variety in different stages of developmentand depicted in color as nearly true as it is reasonably possible tomake the same in a color illustration of this character.

DESCRIPTION OF THE NEW VARIETY

Parentage: Seedling.

Seed parent.--Unnamed, unpatented seedling.

Pollen parent.--Unnamed, unpatented seedling.

Class: Shrub.

The following is a detailed description of the new variety, fromspecimens grown outdoors in Watsonville, Calif., in the month ofSeptember. The color terminology used is in accordance with The RoyalHorticultural Society Colour Chart (R.H.S.C.C.), and refers to platenumbers in the aforementioned color chart. Phenotypic expression mayvary depending on light, environmental and cultural conditions.
